"Geroge and Robert are fantastic gentlemen. I needed a network (ethernet) cable run from the basement to attic because the signal I was getting wasn't strong enough. Robert did a great job. His many years of experience shine through when you watch him work. He did a couple of small holes, ran the cables, tied everything neatly and was gone in 1.5 hours. Thank you very much!!! You gentlemen are lifesavers."

Landline Phone Service questions, answered by experts

While homeowners can make basic repairs with the right tools and knowledge, professional assistance is advisable for complex installations to ensure proper functionality.

Costs depend on panel size, labor, permits, wiring materials, and required safety features.

Regular software updates, checking for loose connections, and protecting wires from physical damage help prevent issues.

It’s a good idea if you receive regular calls from customers, clients, or other important contacts. If phone calls are a daily occurrence for your business, no matter the field, then a separate business line will help you keep things organized. It also gives your business a more professional appearance, improves the security of sensitive business information, can help you manage costs more accurately, and may even be a good idea on the legal front.

The phone jack is the square wall-mounted plate into which a telephone plug is placed for the phone to get service. You’ll know your phone is properly connected to a working phone jack if you hear a dial tone when you pick up the phone. Phone jacks are often silver, white, or beige and are usually located in the living room, kitchen, bedrooms, or dens.
